To all whom it may concern:

Be it known that I, CARY 00X, of (lovington, in the county of Newton and State of Georgia, have invented a new and useful Improvement in Soldering Compound, of. which the following is a specification:

The object of this invention is to improve and simplify the cost of soldering tin, copper, and similar wares; and it consists in a compound or liquid to be used in combination with the solder compound, as hereinafter described.

In carrying out my invention I proceed as follows: I place in a glass jar or other suitable vessel the following substances, viz., sa1- ammoniac, one-fourth of a pound; zinc in small pieces, one pound; sulphate of copper;

one-fourth of a pound now add muriatlc acid,.three pounds. Let the composition stand for about the space of twenty-four hours, uncovered, then pour it off from the dregs, and add three pints of soft water. Shake the compound so as to thoroughly mix the above in gredients and bottle for use. The solder ispreferably used in the form of wire, the end I of which is dipped in the compound, and applied to the heated surface of the article to be soldered.

By this process no soldering-iron is required. 1

The heat is applied by means of the flame of a lamp ofheated iron upon the opposite side; but I do not confine myself to any particular a.

mode of using the compound; nor do I confine myself to the precise proportions named of the ingredients, or mode of combining them.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent--- A compound for soldering, composed substantially as describedthat is to say, by combining n u riatic acirl salzainmoniac, sulphate of copper, Zinc, and' watep,;in about the proportions named. I
